Hi Lisa,
I highly recommend
Chef Mickey's. This fantastic restaurant has a party atmosphere and he'll be able to see Mickey, Minnie, Goofy, Donald and Pluto. There is a great make-your-own ice-cream sundae station there as well.
My son really loved eating breakfast at the
Crystal Palace when he was 5. Actually, he still loves it at 11 ;) You'll see Pooh, Tigger, Eeyore and Piglet here. Tigger is always awesome and makes the kids laugh every time.
Does your little guy like Stitch? If so, Lilo and Stitch dine with guests at the
'Ohana Best Friends Breakfast.
Another great meal is
Donald's Safari Breakfast at the Animal Kingdom Park. It's a lot of fun to see the charactes all decked out in their safari gear. My youngest son especially loves seeing Goofy there, but you will also see Donald, Daisy and Mickey.
Currently, the Monster's Inc. gang does not participate in character meals.
Have a magical time,
Kaylene
